Integrated disengager and stripper (2) for separating solid particles suspended in vapour and for stripping adsorbed and entrained residue from the solid particles comprising: a disengager vessel (3) having a primary fluidized-bed zone (10), and a primary injector (12) for injecting into the primary fluidized-bed zone (10) a gas for fluidizing or stripping solid particles; a vertical primary cyclone (6), which has a cylindrical side wall (15) and is closed at its upper end by means of a cover (17) provided with an outlet opening (19) and open at its lower end, which primary cyclone (6) is further provided with an inlet (24) for receiving a suspension of solid particles and vapour; and a first outlet conduit (30) for providing a flow path from the outlet opening (19) of the primary cyclone (6), wherein the open lower end (32) of the primary cyclone (6) projects downwardly into the primary fluidized-bed zone (10) so as to form a secondary fluidized-bed zone (35) within the open lower end (32) of the primary cyclone (6), and wherein suitably there is provided a secondary injector (41) for injecting into the secondary fluidized-bed zone (35) a gas for fluidizing or stripping solid particles.
